To (all 70/1 om it may concern:

Be it known that I, ALBERT SnNrnR STAN DISH, a citizen of the UnitedStates, residing at Cleveland, in the county of (]nyal1oga and State ofOhio, have invented a new and useful Auto re-Protector, of whichthcfollowing is a specification.

One object of the present invention is to provide a tire protector whichmay be removed readily from the tire.

Another object of be held securely upon the tire.

Another object of the invention is to provide novel means for varying hetension of the resilient devices whereby the protector is held upon thetire.

/Vith the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdcscril'icd and claimed, it being understood that changes in the preciseembodiment of invention can be made within the scope of what departingfrom the spirit ot the invention.

in the drawing :Figure 1 shows the invention in side elevation; Fig. 2is a trans verse section; Fig. is a 'tragmental side eleration upon anenlarged scale; Fig. 4 is a il'ragmcntal top plan; Fig. 5 is a bottomplan of the base plate; and Fig. 6 is a top plan or" the base plate.

in the drawing, the numeral 1 indicates the folly and the numeral 2indicates the tire. l'lxtendcd circuinferentially of the tire is a belt3, which may be fashioned from leather or from any other suitablematerial. Spaced shoes et, preferably fashioned from metal, cxl'endtransversely of the belt 3, the shoes lbeing connected with the belt 3by means of securing elements 5. The shoes 4- are equipped Willianti-skidding projections l3 of any desired form.

lllmmted on one end of each shoe -lis a pivot element 1' upon which atie His mount ed to swing approximately iaralll-l to the median plane ofthe tire r nether tie 5) is shown, the same having an eye It] pivotallyengaged in the other end of the shoe l.

The invention includes a plurality of twopart base members ll, abuttingagainst the inner circumference of the ielly 1, the coin stitutentportions of the base members being the invention is to provnle novelmeans whereby the protector may and associated parts being pivotallyconnected as shown at 50. At the ends of the parts of base members 11are termed spaced wings l2 and 1.4, the wings 12 and 14 extending alongthe side faces of the folly 1, as shown at 15, to prevent the basemembers 11 from moving transversely of the telly l. In one end of thebase member ll, between the wings 14 there is an opening 16, and in theother end of the base member 11, between the wings 12 there is aterminally open notch 17. The basemcmber 11 is provided, at one end, andadjacent the notch 17, with dcpendin projections 18. The tie 8 extendsthrougi the opening 16 and the lie 9 lies in the notch 17.

Compression springs 19 and 20 surround the ties 8 and 9 respectively,the outer end 21 of the former resting on the under face of the basemember 11 adjacent one end of the base plate. The spring 20 whichsurrounds the tie S), abuts against the under face at one end of thebase memberlhthc washer being engaged behind the projections 18. (Jams2&5, preferably of U-shape, as sliownin Fig. 5 are provided, the camsbeing mounted upon pivot elements 524: which extend through the ties Sand 9, adjacent the free ends of the ties. The cams are equipped withflat edge faceslf and 26, either of which may be brought into contactwith washers 27 receiving the inner ends ol the springs 19 and 20.Presupposing that the parts are posi tioncd as shown in Fig. 2, it willbe ol served that the tension of the springs .lSl-and 90 may be adjustedby bringing the faces and 26 ol the cams 23 successively into eugagcnmntwith the washers 27. Thus, the parts ol the base member ll are swungupon their pivotal connections 50, the springs 18) and 20 causing thewings 15 to pinch the sides ol. the folly .1. Further, the hold of theshoes l and the belt 3 upon the tire 2 thus may be varied. liy rotatingthe cams 2:1 upon their pivotal mountings 2 1-, so that either at theFaces 25 and it; bears against the washers 27, the tension ol thesprings l!) and 20 may be released. 'lheroupon. the washer :33 may bemoved toward the center ol the wheel, until the washer lies beyoi'ul theends of the projections 18, whm'eupon the tics 5) may be swung outwardlythrough the" notch 17. Thus it will besccn that the tire protector, atone side, may be disengaged readily troin the base member 11, the basereadily remov-
